Very nice!
On AMD side do you still have 2 GPUs to be able to enable VFIO passthrough ?

Unless you have a high end nvidia gpu, you still need two gpus for passthrough. Nvidia locks consumer cards out of vgpu's arbitrarily. I've seen projects that change the card reported and their software happily provides vgpus. libvf.io is doing excellent work on providing solutions in the case of one GPU. Intel no longer supports passthrough on 10th gen+ igpus and has killed gvt-g. Intel says SR-IOV is the future, but has not provided working code.

No, you don't need two GPUS unless you want to also use your host at the same time, which for some people maybe necessary, but for most people doing VFIO gaming it's not needed. but VFIO works on all GPU's if needing GUI host at the same time is not needed (you can still SSH into host and whatnot)

More of a side note, but I found an RS232 connection (my mobo had a port, though 2x USB -> RS232 is fine too) to be my best friend when doing a GPU passthrough . You'll rarely need it, but when you do need it, you're super glad it's there.
